ath79: add support for Senao Engenius EAP350 v1
FCC ID: U2M-EAP350
Engenius EAP350 is a wireless access point with 1 gigabit PoE ethernet port,
2.4 GHz wireless, external ethernet switch, and 2 internal antennas.
Specification:
- AR7242 SOC
- AR9283 WLAN (2.4 GHz, 2x2, PCIe on-board)
- AR8035-A switch (GbE with 802.3af PoE)
- 40 MHz reference clock
- 8 MB FLASH MX25L6406E
- 32 MB RAM EM6AA160TSA-5G
- UART at J2 (populated)
- 3 LEDs, 1 button (power, eth, 2.4 GHz) (reset)
- 2 internal antennas
MAC addresses:
MAC address is labeled as "MAC"
Only 1 address on label and in flash
The OEM software reports these MACs for the ifconfig
eth0 MAC *:0c art 0x0
phy0 --- *:0d ---
Installation:
2 ways to flash factory.bin from OEM:
- if you get Failsafe Mode from failed flash:
only use it to flash Original firmware from Engenius
or risk kernel loop or halt which requires serial cable
Method 1: Firmware upgrade page:
OEM webpage at 192.168.10.1
username and password "admin"
Navigate to "Upgrade Firmware" page from left pane
Click Browse and select the factory.bin image
Upload and verify checksum
Click Continue to confirm and wait 3 minutes
Method 2: Serial to load Failsafe webpage:
After connecting to serial console and rebooting...
Interrupt uboot with any key pressed rapidly
execute `run failsafe_boot` OR `bootm 0x9f670000`
wait a minute
connect to ethernet and navigate to
"192.168.1.1/index.htm"
Select the factory.bin image and upload
wait about 3 minutes
Return to OEM:
If you have a serial cable, see Serial Failsafe instructions
otherwise, uboot-env can be used to make uboot load the failsafe image
*DISCLAIMER*
The Failsafe image is unique to Engenius boards.
If the failsafe image is missing or damaged this will not work
DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt
ssh into openwrt and run
`fw_setenv rootfs_checksum 0`
reboot, wait 3 minutes
connect to ethernet and navigate to 192.168.1.1/index.htm
select OEM firmware image from Engenius and click upgrade
Format of OEM firmware image:
The OEM software of EAP350 is a heavily modified version
of Openwrt Kamikaze. One of the many modifications
is to the sysupgrade program. Image verification is performed
simply by the successful ungzip and untar of the supplied file
and name check and header verification of the resulting contents.
To form a factory.bin that is accepted by OEM Openwrt build,
the kernel and rootfs must have specific names...
openwrt-senao-eap350-uImage-lzma.bin
openwrt-senao-eap350-root.squashfs
and begin with the respective headers (uImage, squashfs).
Then the files must be tarballed and gzipped.
The resulting binary is actually a tar.gz file in disguise.
This can be verified by using binwalk on the OEM firmware images,
ungzipping then untaring.
The OEM upgrade script is at /etc/fwupgrade.sh
Later models in the EAP series likely have a different platform
and the upgrade and image verification process differs.
OKLI kernel loader is required because the OEM software
expects the kernel to be no greater than 1024k
and the factory.bin upgrade procedure would
overwrite part of the kernel when writing rootfs.
Note on PLL-data cells:
The default PLL register values will not work
because of the external AR8035-A switch between
the SOC and the ethernet PHY chips.
For AR724x series, the PLL register for GMAC0
can be seen in the DTSI as 0x2c.
Therefore the PLL register can be read from uboot
for each link speed after attempting tftpboot
or another network action using that link speed
with `md 0x1805002c 1`.
uboot did not have a good value for 1 GBps
so it was taken from other similar DTS file.
Tested from master, all link speeds functional
